Cost-Benefit Evaluation of Ecoroofs
The City of Portland's Bureau of Environmental Services (BES) investigated the benefits of ecoroofs and concluded that they work well for stormwater management. To date, over 1,000,000 square feet (SF) of ecoroofs or roof gardens have been built in Portland, with more planned in the near future. As part of an effort to understand the implications of widespread installation of ecoroofs throughout the City, this evaluation studied the range of costs and benefits associated with ecoroofs. The analysis compared the performance of an ecoroof with that of a traditional roof on a new five-story commercial building with a roof area of 40,000 SF in downtown Portland. The categories of economic impacts include capital and O&M costs of stormwater management, energy consumption, building construction and O&M costs, amenity values, impacts on climate including carbon reduction, and habitat values. The results of the cost-benefit analysis provide insights into the net economic benefits of ecoroofs and the relative magnitude of private vs. public costs and benefits over time.
